162 W. T. Blanford — On Birds from Sikkim. [No. 2, 
The occurrence of A. arvensis so far to the eastward strongly confirms 
Mr. Blyth’s view of the identity of A. triborhyncha, Hodgs. (Ibis, 1867, 
p. 47) with it. 
560a. PiiYr.i.oscopUS paltudipes, sp. nov. PI. vii. 
P. supra umbrino-olivaceus, uropygio magis rufesoenti ; loris ei lined 
postoculari umbnnis, superciliis albis, postice elongatis ; remigibus umbrinis, 
extus rufeseente olivaceo marginatis, rectricibus mediis cum dorso fere 
concoloribus, carter is umbrinis, olivacco-marginatis ; gastro sericeo-albo, 
pectoris lateribus olivaceis, axilld albu ; rostro supra fusco, infra pallido ; 
pedibus albescentibus. Long, alas 2 '05, caudae 17, tarsi 0 76, rostri a fronte 
0'4, a rictu 0'55 unc. 
Brownish olivaceous above, supercilium white, extending far back, a 
dark line from the lores through the eye to the upper part of the ear coverts, 
the lower portion of which are light brown, central rectrices very little darker 
than the back, outer rectrices and wing feathers earthy brown, margined with 
olive which is rufescent on the edges of the quills. There is also a rufescent 
tinge on the rump. Lower parts silky white, sides of the breast dusky 
olivaceous, and the middle of the breast not quite so fine a white as the 
throat and abdomen, but this may be an individual peculiarity. Lower 
wing coverts, axillaries, and forepart of wing white. Bill dark above, pale 
below ; feet very light coloured. The fifth quill is the longest, it exceeds the 
first by 0-87 in., the second by 04, the third by 015. 
This form of which a single example in beautiful order has been sent 
by Mr. Mandelli appears to me quite new. It is near P. neglectus, Hume, 
Ibis, 18/0, p. 143, but differs in its olivaceous tint above, smaller size and 
in the very pale coloured tarsi and feet. It is also quite distinct from 
P. tristis, Bl., P.fuscatus, Bl., P. lugubris, Bl., and from the various species 
described from China by Mr. Swinlioe, P. tenellipes , Swinh., alone resembling 
it in its pale feet, but differing in colour. 
Beocloides sp. ? 
A single specimen from Mr. Mandelli’s collection closely resembles It. 
proregulus, Pall. (B. chloronotus, Hodgs.) in appearance and size, and has a 
similar minute bill though a little broader and more Abrornis- like, but the 
head is dusky grey, almost black, with a white central line and white 
supercilia, a distinct dusky line from the lores through the eyes ; cheeks, 
throat and breast greyish white, lower breast and abdomen pale yellow, the’ 
two outer tail feathers on each side have the whole inner web white, and’ the 
third has nearly the whole, a very narrow border inside the web near the tip 
emg brown, but the tip of the inner web itself white, not dark as in It.
